Answer:

7x^2 -12x(sqrt 14) + 72

Step-by-step explanation:

Use foil and you get

x^2(7) - (3x(sqrt56))+(-3x(sqrt56))+ 9(8)

= The inner terms simplify to -6x(sqrt14) + (-6x(sqrt14)) = -12x(sqrt14)

so answer is

7x^2 -12x(sqrt 14) + 72

Answer:

D. Multiply the second equation by 3. The solution is x = 12, y = 10.

Step-by-step explanation:

First, look at the y variable of the first equation. It is 3y.

To solve by elimination, the variables have to add together to 0.

So, -3y needs to be added to -3y to eliminate the y variable.

The second equation has the y variable of -y, so it has to be multiplied by 3.

So, answer choice D is the correct answer.

Answer:

After 30 years 204 g of the substance will be left.

Option C is correct option.

Step-by-step explanation:

The function given is: [tex]A=600e^{-0.036t}[/tex]

where t is time in years.

We need to find how much of the  substance will be left in the sample after 30 years?

So, we have t= 30

Putting value of t and find value of A

[tex]A=600e^{-0.036t}\\A=600(\frac{1}{e^{0.036*30}})\\A=\frac{600}{e^{1.08}} \\A=\frac{600}{2.94467}\\A=203.75 \approx 204[/tex]

So, After 30 years 204 g of the substance will be left.

Option C is correct option.

Answer:

The expected value is -$0.17

Since it gives a negative expected value, the game is not favorable and should not be played

Step-by-step explanation:

Here, we want to calculate the expected game value and decide if the game is worth playing

Probability of rolling a six is 1/6

Probability of rolling a 5 is 1/6

Probability of rolling a number less than 5 is 4/6 = 2/3

So the only way to win is rolling a six

The expected value is thus;

1/6(3) - 0(1/6) - 2/3(1)

= 1/2 - 2/3

= -$0.17

Since the game gives a negative expected value, it is not favorable and should not be played

In this exercise we want to use probability to calculate the value we will have in total after the event occurs, like this:

The value is -$0.17, with thw negative value, the game should not be played.

Let's organize the information given in the statement, in this way, we will have to:

With this combination of values, we find that the probability will be calculated as:

[tex]1/6(3) - 0(1/6) - 2/3(1)= 1/2 - 2/3\\= -$0.17[/tex]

Answer:

x is 11

Step-by-step explanation:

We know the slope (3/4) and a point (3,-4), so we can use point-slope form (y-y1=m(x-x1)

Substitute the numbers into the equation

y--4=3/4(x-3)

simplify

y+4=3/4(x-3)

do the distributive property

y+4=3/4x-9/4

subtract 4 from both sides

y=3/4x-25/4

this is the equation of the line.

Since it says that (x,2) is a point in the equation, we can substitute it into the equation

2=3/4x-25/4

add 25/4 to both sides

33/4=3/4x

multiply by 4/3

11=x

we can double check by plugging (11,2) into the equation of the line.

2=3/4(11)-25/4

2=33/4-25/4

2=2

it works! :)

Hope this helps!

Answer:

p1 = F

p2 = D

Step-by-step explanation:

The following are matched.

P4 - Linear Pair

P3 - Vertical Angles

P6 - Angle Bisector

P2 - Parallel Lines

P5 - Ortho Center

P1 - Centroid

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Answer:

287 inches so rounding its 290 inches

Answer:

Jenny cycles the grand distance of 29 and one third of a mile.

Step-by-step explanation:

I want to answer this using fractions and without multiplying by an awkward recurring decimal.

Cycling 11 miles in 45 minutes and continuing at the same speed means she will go 22 miles in 90 minutes

To scale up 90 mins to the required 120 mins (2 hours) multiply by 4/3.

22 x (4/3) = 88/3

Jenny will travel 88/3 miles in 2 hours.

Not happy with top heavy fractions?

Let's round up 88/3 to 90/3 by adding 2/3.

90/3 = 30 and to get back to the answer we just take away the two thirds we added when rounding up.

Jenny cycles the grand distance of 29 and one third of a mile.

I think that is the correct answer.
